SPRING-BED AND SPRING.

SPECIFICATION forming part of Letters Patent No. 273,401, dated March 6,1883. Application filed January 16,1883. (No model.)

To all whom it may concern: Be itknown that 1, JAMES H. SHIELDS, acitizen of the United States, residing at Boston, in the county ofSufl'olk and State of Massachusetts, have invented new and usefulImprovements in Spring-Beds and Springs therefor, and forupholsteringpurposes,of which the following is a specification.

This invention relates to improvements in spring-beds and springstherefor,and for upholstering purposes; and it consists in the novelmanner of constructing the springs of the bed, and their combinationwith the mattress-supporting bars thereof, and the means for supportingthe latter by the bed-frame.

In the drawings forming part of this specification, Figure I is a sideelevation, partly in section, and Fig. II is a plan view, with some ofthe mattress-bars removed, of a bed embodying my combined improvements.Fig. III is a side elevation, and Fig. IV an end View, of my improvedbed and upholsteryspring, and Fig. V is an edge view of the main part ofthe same.

In the drawings, A is the bed-frame. Z) indicates the mattress-bearingbars. 0 indicates the springs entire; 0, the main part thereof, and ithe strengthening or auxiliary blades thereof. n m are bearing-platessecured to 0 each end of the springs c. c are straps on the ends of thebars I), and 00 are spring-hooks secured to the end railsot' thebed-frame A.

The spring 0 consists of the part 6, made from an elastic, springy,metallic band, bent intoa 5 form resembling an S, or a succession ofsuch forms, and having the bearing-plates n m secured to each endthereof, (one or.n1ore,) to provide a bearing-surface of' greaterereathan the end of the spring alone would afford. Said 40 pieces n m maybereplaced by one of disk form or square, as preferred. Between thefolds of the said part care secured the sin gle-bend auxiliarystrengthening-blades i, as shown, one end. of which is free and adaptedto come to a 5 bearing upon the part c of the spring under it when thelatter shall have been'somewhat compressed, whereby, to acertain degree,the

, edges of the springs in one row standing opposite the sides ofthose-in the adjoining row,

as shown in Fig. 11. The end rails of the frame A are provided withmetallic spring-hooks w, to which the bearing-bars b are hung by meansof thin metallic or leather straps '0, secured to each end of said bars,and the upper ends of the springs c are secured to the under side ofsaid bars by screws passing through said plates n m, one or both.

The spring-bed, constructed as aforesaid. is one of easy elasticity, andthe force of the springs 0, under the bars I), is supplemented by thespring force of the books a, after a certain amountof depression hasbeen given to the mattress-bearing bars I). Said springs 0, when arranged'in a similar manner in the seats of furniture, provide a desirableupholstery spring.

What I claim as my invention isp 1. The within-described improvedspring-bed,

consisting of the frame A, having the springhooks a0 thereon, the barsI), secured by their ends to said hooks, and the springs 0, consistingof the part c, bent in a succession of 8 forms, and having securedbetween the folds thereof the auxiliary blades 2', said springs beingsecured between the bottom of said frame and said bars, as set forth.

2. The within-described improved bed and upholstery -spring 0,consisting of the main part e,madefrom an elasticmetallic band bent intoa succession of 8 forms, and having secured by one end, between itsfolds,the auxiliary blades 6, and'having one or more bearingplates oneach end thereof, all as set forth.

JAMES H. SHIELDS.
